Collectable Antique Brass Perpetual good Calendar// K&Co 1928

This small antique calendar is suitable for both your pocket and adorned good on your desk.

There is a stamp on the back which is marked as "patented K&Co Feb 21-28".

To change the month you turn the brass knob at the bottom which says the amount of days in the month. To change the day you simply push the numbers along to match the day of the week in that month.

Overall the condition is fair vintage, but it could do with a polish up with some Brasso.

It measures 8cm by 5.2 cm.
